R-values for rigid insulation vary from R-3.85 to R-6.8 per inch of thickness. Polyiso has the highest R-value, followed by XPS and EPS. The key to all rigid insulation high R-values are small air pockets that exhibit high thermal resistivity properties: Small air pockets visible in Styrofoam.

3 kwi 2023 · R-Value of EPS Rigid Insulation. When it comes to choosing the best insulation to cover a building envelope, it’s less about the shape of the material and more about its properties and performance. One measure to compare is the thermal resistance value, or R-value.
The range of R-values of insulation materials spans from materials with R-10 insulation values per inch like vacuum insulated panels and silica aerosol to below R-1 values per inch like bricks, glass, and poured concrete.
LONG TERM INSULATION VALUE R-value means the resistance to heat flow. The higher the R-value the greater the resistance to heat flow. The thermal perfor-mance of EPS insulation, as with any insulation product, depends upon the correct installation using good building practice. When properly installed, the R-value of EPS insulation remains constant
From metal panels insulated with polyisocyanurate (PIR) and polyurethane (PU) systems to composite panels fortified with halogen-free, flame-retardant core layers, our broad range of insulation product offerings are customizable to your specifications and offer superior levels of efficiency and performance for both commercial and residential ...
Discover the importance of R-Value in selecting insulation materials. Explore how EPS rigid foam insulation can enhance thermal performance in your projects with Alleguard's range of high-efficiency solutions.
R-Value is a measure of insulation’s ability to resist heat traveling through it. The higher the R-Value the better the thermal performance of the insulation. The table below shows what levels of insulation are cost-effective for different climates and locations in the home.
